Systematic LLM Translation of Legacy Scientific Code to Differentiable Frameworks: Application to a Land Surface Model
Researchers developed an LLM-based pipeline that automatically translates legacy Fortran scientific code into JAX, a differentiable programming framework. Applied to a 19,000-line land surface model, the approach achieved 24x speedup and 8x faster parameter optimization while enabling gradient-based analysis through automatic differentiation.
